Multi-family office regulatory landscape in 2026: jurisdiction-by-jurisdiction

The question of which jurisdiction offers the most stable regulatory environment for a multi-family office is no longer abstract for principals who manage concentrated wealth across borders. After the Swiss Federal Council published its revised Anti-Money Laundering Ordinance on 1 January 2026, bringing all family offices that manage assets exceeding CHF 5 million under direct FINMA supervision, the calculus shifted materially. The UAE followed in February 2026 with Cabinet Resolution No. 12, mandating that any multi-family office operating from the Abu Dhabi Global Market or Dubai International Financial Centre must register with the newly formed Family Office Regulatory Authority (FORA). These two changes alone affect an estimated 1,400 multi-family offices globally, according to the Family Office Exchange’s 2025 benchmarking survey, and they are not isolated. The year 2026 is the first in which a majority of the world’s top ten wealth-hosting jurisdictions have enacted or are enacting dedicated family office legislation, moving the sector from a lightly regulated advisory niche to a formally supervised financial services category. ## The Swiss shift: FINMA supervision and the CHF 5 million threshold Switzerland’s revised AML Ordinance, published in the Federal Gazette on 15 December 2025 and effective 1 January 2026, reclassifies any family office that manages assets of CHF 5 million or more as a financial intermediary subject to direct FINMA supervision. Previously, family offices could operate under self-regulatory organisations or remain unregulated if they served only a single family. The new threshold captures an estimated 320 multi-family offices in Geneva, Zurich and Lugano, according to the Swiss Family Office Association’s 2025 membership data. ### The cost of compliance under the new regime The direct cost of FINMA authorisation for a multi-family office is CHF 25,000 in application fees, with annual supervisory fees starting at CHF 12,000 for offices managing under CHF 50 million in AUM. These figures are drawn from FINMA’s updated fee schedule published on 1 December 2025. Indirect costs include mandatory appointment of a compliance officer with a Swiss residency requirement, quarterly AML reporting, and external audit of AML controls. Industry estimates from the Swiss Family Office Association suggest total annual compliance costs for a mid-sized multi-family office will rise by 40-60 percent, from approximately CHF 80,000 to between CHF 112,000 and CHF 128,000. ### Structuring options that remain viable Despite the tighter regulatory net, Switzerland retains structural advantages for multi-family offices that serve non-Swiss resident principals. The holding company regime under article 75 of the Swiss Federal Tax Act continues to allow full participation exemption on capital gains and dividends from qualifying subsidiaries. A multi-family office structured as a Swiss corporation with a paid-in capital of CHF 100,000 can still benefit from the effective corporate tax rate of 11.9 percent in Zug and 12.3 percent in Geneva, as of the 2026 cantonal tax schedules. The key change is that the office must now hold a FINMA licence, which requires its directors to demonstrate professional qualifications equivalent to those of a Swiss asset manager under the Collective Investment Schemes Act. ## The UAE: FORA registration and the two-tier model The UAE’s Cabinet Resolution No. 12 of 2026, published in the Federal Official Gazette on 10 February 2026, establishes the Family Office Regulatory Authority as a standalone regulator within the Abu Dhabi Global Market. The resolution applies to any multi-family office that provides asset management, estate planning, or fiduciary services to more than one family and has its principal place of business in the ADGM or DIFC. FORA registration is mandatory, with a non-refundable application fee of AED 50,000 and an annual licence fee of AED 100,000. ### The ADGM versus DIFC distinction The ADGM’s FORA regime imposes a minimum AUM threshold of AED 50 million (approximately USD 13.6 million) for multi-family offices, while the DIFC has elected to maintain its existing regulatory framework under the Dubai Financial Services Authority but with a new notification requirement. The DIFC’s approach, detailed in its March 2026 consultation paper, requires multi-family offices to file an annual compliance statement but does not subject them to the same capital adequacy requirements as the ADGM. For a multi-family office managing USD 20 million in assets, the ADGM route requires a minimum capital of AED 1 million held in a segregated account, while the DIFC route requires no minimum capital but mandates professional indemnity insurance of at least AED 5 million. ### Substance requirements and the economic reality test Both the ADGM and DIFC now enforce a substance test that requires the multi-family office to maintain a physical office, employ at least three full-time staff including a senior executive who is a UAE resident, and hold board meetings in the jurisdiction at least four times per year. These requirements are codified in the ADGM’s Economic Substance Regulations (Amendment No. 3) of 2026 and the DIFC’s equivalent directive issued on 15 March 2026. The penalty for non-compliance is a fine of up to AED 500,000 and potential revocation of the licence. For a family office that previously operated a mailbox structure in the DIFC, the substance requirement represents a material operational cost increase of approximately USD 150,000 per year in rent, salaries and travel. ## Singapore: the variable capital company and the MAS notice Singapore’s Monetary Authority of Singapore issued MAS Notice SFA 04-N22 on 1 November 2025, effective 1 January 2026, which subjects all multi-family offices managing assets exceeding SGD 250 million to licensing as fund management companies under the Securities and Futures Act. The threshold is significantly higher than Switzerland’s CHF 5 million, meaning the majority of Singapore’s estimated 200 multi-family offices remain exempt from direct MAS licensing. However, the notice introduces a mandatory annual notification requirement for all family offices, regardless of AUM, with a filing fee of SGD 1,000. ### The variable capital company as a structuring vehicle Singapore’s variable capital company regime, introduced under the Variable Capital Companies Act of 2018 and amended in 2025, remains the preferred structuring vehicle for multi-family offices that pool assets from multiple families. The VCC allows for ring-fenced sub-funds, each with its own portfolio of assets and separate liability. The 2025 amendment reduced the minimum initial capital requirement for a VCC used by a multi-family office from SGD 250,000 to SGD 50,000, making it accessible for smaller multi-family offices. The annual filing fee with the Accounting and Corporate Regulatory Authority is SGD 800 per sub-fund, with a cap of SGD 5,000 for VCCs with more than ten sub-funds. ### The 13O and 13U tax incentive schemes The MAS’s updated tax incentive schemes under sections 13O and 13U of the Income Tax Act remain available for multi-family offices that meet the enhanced conditions introduced in 2025. For a 13O scheme, the minimum AUM is SGD 20 million, with a requirement to employ at least two investment professionals who are Singapore residents. The application fee is SGD 1,500, and the scheme provides a full tax exemption on specified income. The 13U scheme, for larger offices with AUM of SGD 50 million or more, requires three investment professionals and an annual business spending of at least SGD 200,000. The MAS’s 2025 annual report indicates that 1,200 applications were approved under both schemes in the financial year ending March 2025, with a rejection rate of 8 percent. ## Luxembourg: the reserved alternative investment fund manager Luxembourg’s Commission de Surveillance du Secteur Financier introduced a dedicated family office regime on 1 July 2025, codified in CSSF Regulation 25-05. The regime allows multi-family offices to operate as reserved alternative investment fund managers, a classification that exempts them from the full AIFMD requirements provided they manage assets below EUR 100 million and serve no more than ten families. The RAIFM status requires a minimum capital of EUR 50,000, down from the EUR 125,000 required for a full AIFM licence. ### The tax transparency advantage A Luxembourg multi-family office structured as a RAIFM can elect to be treated as a tax-transparent entity under article 48 of the Luxembourg Income Tax Law, meaning the office itself pays no corporate income tax on its investment income. Instead, each family member is taxed on their proportionate share at their individual residence rate. This structure is particularly advantageous for families with members resident in multiple jurisdictions, as it avoids the double taxation that can arise when a corporate entity pays tax on gains that are later distributed. The CSSF’s 2025 guidance note confirms that a RAIFM can hold real estate, private equity, and listed securities within the same structure without triggering additional regulatory requirements. ### Substance requirements and the Luxembourg economic substance law The Luxembourg law of 27 December 2024 on economic substance requires any RAIFM to maintain a physical office in Luxembourg, employ at least two full-time staff who are Luxembourg residents, and hold at least one board meeting per year in the jurisdiction. The law applies equally to multi-family offices and commercial fund managers. The penalty for non-compliance is a fine of up to EUR 250,000 and potential revocation of the RAIFM status. For a family office that previously operated from a serviced office with a single director, the substance requirement adds an estimated EUR 80,000 to EUR 120,000 in annual operating costs. ## The United States: state-by-state divergence and the SEC’s private fund rules The United States presents a fragmented regulatory landscape for multi-family offices, with no federal family office regime and significant variation among states. The SEC’s Private Fund Adviser Rules, adopted in 2023 and upheld by the D.C. Circuit Court in 2025, apply to any multi-family office that manages assets of USD 150 million or more and provides investment advice to more than 15 families. The rules require quarterly reporting, annual audits, and a ban on certain preferential treatment of specific investors. ### The family office exemption under the Investment Advisers Act Section 202(a)(11)(G) of the Investment Advisers Act of 1940 provides an exemption for family offices that meet three conditions: the office must be wholly owned by a single family, must not hold itself out as an investment adviser, and must not advise any client other than family members. The SEC’s 2018 interpretive release confirmed that this exemption applies only to single-family offices, not multi-family offices. Any multi-family office in the United States is therefore a registered investment adviser unless it qualifies for an alternative exemption, such as the venture capital fund exemption under rule 203(l)-1 or the private fund exemption under rule 203(m)-1. ### State-level advantages: South Dakota, Delaware and Nevada South Dakota’s trust code, codified in title 55 of the South Dakota Codified Laws, remains the most favourable for multi-family offices that structure their assets through directed trusts. The state permits perpetual trusts with a duration of up to 1,000 years, no state income tax on trust income, and the ability to appoint a trust protector with broad powers to modify the trust. Delaware’s statutory trust act under title 12 of the Delaware Code allows for the creation of series trusts, where each family’s assets are held in a separate series with distinct creditors. Nevada’s asset protection trust statute, codified in chapter 166 of the Nevada Revised Statutes, provides the strongest domestic asset protection, with a two-year statute of limitations for creditor claims. ## A composite case study: the Constantinopoulos family office The Constantinopoulos family, a Greek shipping dynasty with a net worth of approximately USD 450 million, established a multi-family office in 2022 to serve three branches of the family. The office managed USD 180 million in liquid assets and USD 70 million in direct real estate holdings across Greece, Switzerland and Singapore. In early 2026, facing the Swiss FINMA threshold and the UAE’s FORA registration, the family’s advisors evaluated four jurisdictions. ### The Swiss option with FINMA licence The advisors calculated that maintaining the Swiss structure would require a FINMA licence, with annual compliance costs of CHF 125,000 and the need to appoint a Swiss-resident compliance officer. The Swiss corporate tax rate of 12.3 percent in Geneva would apply to the office’s management fees, but the participation exemption under article 75 of the Swiss Federal Tax Act would shelter capital gains on the family’s shipping investments held through a Swiss holding company. The total annual cost, including compliance and tax, was estimated at CHF 185,000. ### The Singapore option with 13O scheme Relocating the office to Singapore would require establishing a VCC with three sub-funds, one for each family branch, at a total setup cost of SGD 45,000. The 13O tax incentive would provide full exemption on specified income, and the MAS’s notification requirement under SFA 04-N22 would apply only if AUM exceeded SGD 250 million, which it did not. The annual operating cost, including the VCC filing fees and the salary of two Singapore-resident investment professionals, was estimated at SGD 280,000. ### The UAE option with ADGM FORA registration The ADGM route required a minimum capital of AED 1 million and an annual licence fee of AED 100,000, plus the cost of a physical office and three full-time staff. The total annual cost was estimated at AED 850,000, or approximately USD 231,000. The UAE’s zero percent corporate tax rate for qualifying holding companies under Cabinet Resolution No. 100 of 2024 would apply to the office’s management fee income, making this the most tax-efficient option. ### The final decision The Constantinopoulos family chose to maintain the Swiss structure for its shipping assets, which were already held through a Swiss holding company, and to establish a second multi-family office in the ADGM for its liquid asset management. The dual structure added approximately USD 120,000 in annual costs but provided regulatory diversification and access to both the Swiss and UAE tax regimes. The family’s advisors noted that the decision was driven primarily by the need to separate the shipping assets, which required Swiss maritime law expertise, from the liquid assets, which benefited from the UAE’s zero-tax regime. ## Five planning steps for multi-family office principals The first step for any principal evaluating a multi-family office structure in 2026 is to commission a jurisdiction-specific regulatory audit that maps the office’s current AUM, number of families served, and asset types against each jurisdiction’s licensing thresholds and substance requirements. The second step is to quantify the total cost of compliance under each jurisdiction’s new regime, including direct fees, indirect costs such as staffing and office space, and the opportunity cost of capital tied up in minimum capital requirements. The third step is to assess the tax efficiency of each structure by modelling the effective tax rate on management fees, investment income, and capital gains under the jurisdiction’s holding company or tax transparency regimes. The fourth step is to evaluate the substance requirements as a practical operational constraint, particularly for families that do not have existing physical presence or staff in the target jurisdiction. The fifth step is to consider a dual-jurisdiction structure that separates illiquid assets, such as real estate or operating businesses, from liquid financial assets, allowing each asset class to be held in the jurisdiction with the most favourable regulatory and tax treatment. ## Sources - Swiss Federal Council, Revised Anti-Money Laundering Ordinance, Federal Gazette 2025-12-15, effective 1 January 2026 - FINMA, Fee Schedule for Financial Intermediaries, 1 December 2025 - UAE Cabinet Resolution No. 12 of 2026, Federal Official Gazette, 10 February 2026 - ADGM, Economic Substance Regulations (Amendment No. 3), 2026 - DIFC, Directive on Family Office Notification, 15 March 2026 - Monetary Authority of Singapore, MAS Notice SFA 04-N22, 1 November 2025 - Monetary Authority of Singapore, Annual Report 2025, section on 13O and 13U schemes - Luxembourg CSSF, Regulation 25-05 on Reserved Alternative Investment Fund Managers, 1 July 2025 - Luxembourg Law of 27 December 2024 on Economic Substance - SEC, Private Fund Adviser Rules, adopted 2023, upheld by D.C.
